FIGS. 3-5 show various diagrams of general image displays that may beutilized with a variety of consumer electronic devices, such as adesktop display, in accordance with the invention and having a housing11, a display 22 associated with housing 11, i.e. mounted on or in thehousing 11, and at least one analog sensor 26 having a depressiblesurface area associated with the display. Analog sensors 26 can beganged in 2-way and 4-way units such as rockers 14, 16 and 18, or can bein single button or surface form such as shown at 19 in some of thedrawings. The analog sensor 26 in a preferred structure has apressure-sensitive variable-conductance material for providing avariable signal varying with differing amounts of user finger appliedpressure, however, the associated circuitry can be structured toadditionally read a rapid press and release on the sensor as amomentary-On used to supply a single increment signal, e.g., single stepnumeric increase/decrease or scroll up/down. As the user's fingerdepresses the sensor material, its conductivity is read by associatedcircuitry, such as a microcontroller, reading the time of charge ordischarge of a capacitor as determined by the conductivity of the analogsensor material. The devices that may be utilized with the presentinvention already have internal microcontrollers or even more complexcircuitry, and one of average skill in the art can readily apply theanalog buttons/sensors/analog rockers/analog membrane sensors to theindicated art with an understanding of this disclosure.

FIG. 1 shows an exploded view of a 2-way analog rocker 14 or 16 as maybe employed in embodiments of the invention as an analog sensor 26.Shown is a circuit board 40 with exposed interdigitated circuit traces44 as a common, 42, 46 as outs or switch legs; two “pills” or disks ofpressure-sensitive variable-conductance material 38; two rubber-domecaps 36 positioned beneath a 2-way rocker member 30. The 2-way rockermember 30 has a first depressible surface 32 and a second depressiblesurface 34. Each finger depressible surface 32, 34 for functioning bydepression with the shown respective dome-caps 36, pills 38 and thecircuit traces 42, 44, 46. It does not require a rocker to electricallyachieve that which is accomplished with a 2-way or 4-way, 14, 16, 18rocker, as two separate or four separate depressible buttons or surfaces(see FIG. 2) can be used although I prefer the rocker format for ease oflocating desired direction oriented depressible surfaces simply by feelwithout having to look.

FIG. 2 shows an exploded view of a 4-way analog rocker 18 as may beemployed in the embodiments of the current invention. Shown is a circuitboard 40 with exposed circuit traces indicated at 62 for four sensors26. Also shown are four pressure-sensitive variable-conductance pills orelements 38; a 4-way rubber-dome cap unit 56 with each of the 4 domecaps 60 support by base 58 over a “pill” or disk of pressure-sensitivevariable-conductance material 38; and a 4-way rocker member having afirst surface 48, a second surface 50, and third surface 52, and afourth depressible surface 54. Each surface for functioning bydepression with the shown respective dome-caps 60, pills 38 andcircuitry 62 of the board 40. This disclosure discloses that which canbe viewed from numerous points, but clearly herein described areimproved methods, structures, and also methods of manufacturing inaccordance with the present invention.

FIGS. 3-5 show block diagrams in accordance with the invention.Illustrated is a housing 11 containing two sensors 26, one sensor 26having depressible surface 80 and the other sensor 26 having depressiblesurface 82. The sensors 26 are connected to circuitry 53 connected to adisplay 22. Also illustrated is a box representing a human user 72 withthe user's eye 74 receiving visual feedback from display 22. The visualfeedback received by the eye 74 at least in part influences thedepressive pressure exerted by the user's finger 76 against sensor 26which in turn is read by circuitry 53 which controls the visual feedbackdisplayed on display 22, thus a closed loop feedback system isestablished in which the user 72 receives immediate feedback concerningthe control of the electronic device according to the invention. Thestate of circuitry 53, as controlled by the user, can control otherfunctions 78 of the electronic device.

FIG. 3 shows display 22 as a general image display. The general imagedisplay 22 of includes an upper area and a lower area, thus a user mayscroll data at varying rates from the lower area to the upper area bypressing surface 80, and from the upper area to the lower area bypressing surface 82.

FIG. 4 shows display 22 having two seven segment numeric displays 28,thus the user may select numbers at a variable rate by varyingdepression on sensors 26. For example, such selection may be for numberof copies to be made by a photocopy machine, temperature setting of athermostat, channel number on a television and the like. Depression ofsurface 80 is arranged in this example to cause a variable rate ofascending numbers according to the level of depressive pressure appliedto surface 80. Depression of surface 82 is arranged in this example tocause a variable rate of descending numbers according to the level ofdepressive pressure applied to surface 82.

FIG. 5 shows display 22 having three seven segment numeric displays 28as are commonly used in time displays. Thus the user may select at avariable rate, numbers representing timing, by varying depression onsensors 26. In FIG. 5, depression of surface 80 is arranged in thisexample to cause a variable rate of ascending numbers representing timeaccording to the level of depressive pressure applied to surface 80, anddepression of surface 82 is arranged in this example to cause a variablerate of descending numbers according to the level of depressive pressureapplied to surface 82, or surfaces 80 and 82 can be arranged to controlhours and minutes individually. Clearly a clock can be greatlyadvantaged by ascending and descending sensors 26 for both hours andminutes adjustments.

FIG. 6 shows a video recorder having a housing 11 and a display 22mounted within housing 11. The display 22 can be any suitable displaypreferably a Non-CRT display. U.S. Class 345 contains many prior artpatents describing Non-CRT displays for those wishing more informationthereon. At the lower center portion of the housing are shown two 2-wayanalog rockers 14 and 16. Shown at the lower left center of housing 11is a 2-way analog rocker 16 which can serve as an X-axis or horizontalcontrol or scroller, and at the lower right center of housing 11 isshown a 2-way analog rocker 14 which can serve as a Y-axis or verticalcontrol or scroller. The rocker depressible surfaces operate analogsensors 26 or from another view form components thereof. For example,the 2-way analog rocker 16 maybe utilized to scroll at variable speedthrough the digital images recorded enabling the viewer to view theimages at a desired rate of speed. Correspondingly, the 2-way analogrocker 14 may be utilized to scroll through at variable speed thecontrol commands appearing on the electronic display to modify thedigital images stored in memory or to adjust the digital camerasfunctions for recording of future images, such as for example shutterspeed and aperture opening.

FIG. 7 shows a digital camera having a housing 11 and a display 22mounted within housing 11. The display 22 can be any suitable displaypreferably a Non-CRT display. U.S. Class 345 contains many prior artpatents describing Non-CRT display for those wishing more informationthereon. U.S. Class 396 contains many prior art patents describingcameras for those wishing more information thereon. At the lower centerback side of the camera housing are shown two 2-way analog rockers 14and 16. Shown at the lower left center of housing 11 is a 2-way analogrocker 16 which can serve as an X-axis or horizontal control orscroller, and at the lower right center of housing 11 is shown a 2-wayanalog rocker 14 which can serve as a Y-axis or vertical control orscroller. The rocker depressible surfaces operate analog sensors 26 orfrom another view form components thereof. For example, the 2-way analogrocker 16 maybe utilized to scroll at variable speed through the videoimages recorded enabling the viewer to view the images at a desired rateof speed. Correspondingly, the 2-way analog rocker 14 may be utilized toscroll through at variable speed the control commands appearing on theelectronic display to modify or adjust the recording of future videoimages. Alternatively, the 2-way analog rocker 16 maybe utilized toscroll at variable speed through the digital images recorded enablingthe viewer to view the images at a desired rate of speed.Correspondingly, the 2-way analog rocker may be utilized to control therate of speed at which the video recorder zooms in on or away fromsubject matter being recorded. In addition, it may also be utilized as aslow motion variable speed control for viewing the recorded videoimages. Further two 2-way analog rockers or one 4-way analog rocker maybe utilized to scroll along the x-axis and y-axis of a recorded image tolocate, mark, identify, enhance, enlarge or modify that particularlocation in the recorded image.

For all embodiments shown herein, the 4-way analog rockers 18 can eachalso serve as X-axis or horizontal control, and as Y-axis or verticalcontrol or scroller manipulated by the user's thumb and or fingers(digits). It is anticipated that the 4-way analog rocker serves largelythe same purposes as two perpendicular 2-way analog rockers, and whilethe embodiments shown herein demonstrate both 2-way and 4-way rockers,for most purposes an embodiment will need only one 4-way rocker or oneor more 2-way rockers, or an equivalent number of single analog pushbuttons.

The present electronic devices utilize analog sensors and circuitry forreading at least three readable states, analog values or conductancelevels of each of the analog sensors; the states, values, levels or thelike may be or can be varied voltages or currents (example only), andare varied dependant upon depressive pressure applied to a fingerdepressible button associated with each analog sensor. Button may beherein treated as the finger depressible area of a rocker member such asa 2-way or 4-way or the like. The associated circuitry is structured toread an immediate, instant or current state or value of the analogsensors and to communicate representative control signals. The at leastthree states of the active element (analog sensor) can represent atleast: 1) no pressure, 2) low pressure, and 3) high pressure applied tothe depressible surface by the human user's finger or thumb (digit), the3 level equating to rates of change. The analog sensor and circuitryarrangement can be employed in a manner wherein not just three but manystates are read, thus ensuring high resolution reading of a variablychanging depressive button pressure input. Preferably, many differentuser determinable rates (many different states rate by the circuitry)are provided between low and high pressure on the associated button sothat the user is provided, for example, very slow, slow, medium, fastand very fast change rates. With the analog sensors, the user isprovided variable change rate control dependant upon the degree ofdepressive pressure he or she applies to the button associated with theanalog sensor(s) which is indicated or made visually detectable on thedisplay at least at the time the analog sensor is being depressed, andthis to allow the intelligent application of finger pressure by the userto the analog sensor. Based on the information shown on the associateddisplay, the user can choose to increase, decrease or terminate fingerpressure on the analog sensor. Such an arrangement provides the uservastly improved control by allowing the user to apply low pressure tohave a slow rate of change, or to apply high pressure to initiate veryrapid change, and then to reduce the applied pressure to the button toreduce the rate of change in order to stop easily and precisely on adesired target or within a desired area, such precise control is clearlyadvantageous and desirable.

The invention can be viewed or defined in numerous ways includingstructure and methods as those skilled in the art will realize upon areading of this disclosure presented to exemplify rather than limit theinvention. Thus, the invention should be defined by the broadestpossible interpretation of the claims.
